Adverse childhood experiences (ACEs) are among the leading environmental causes of morbidity and mortality. Extending research on within-generation effects, more recent scholarship has explored between-generation consequences of ACEs. Despite growing interest in the intergenerational effects of parents’ ACEs on children’s outcomes, this line of scholarship has yet to be coalesced into a comprehensive review. The current study is a scoping review on the intergenerational transmission of parental ACEs and children’s outcomes. Ten databases such as PubMed, APA PsycArticles, and Social Work Abstracts were searched. To be included, empirical studies must have been published in English and analyzed associations between a cumulative measure of at least four parental ACEs and children’s outcomes. Sixty-eight studies qualified for the review and, among these, 60 were published in the most recent 5 years (2018–2022). Fifty-one studies had sample sizes smaller than 500, and 55 focused on the effect of maternal ACEs. Nearly all studies demonstrated that parental ACEs could affect children’s outcomes directly or indirectly via mechanisms like maternal mental health problems or parenting-related factors. By scoping the extant literature, this review advances the knowledge base regarding the intergenerational impacts of parental childhood trauma and children’s outcomes. It also reveals methodological limitations that should be addressed in future research to strengthen causal inferences along with practical implications for interventions that aim to interrupt the intergenerational transmission of trauma.

Despite the persistent hypothesis that adverse childhood experiences (ACE) have intergenerational implications, empirical research documenting the effects and the mechanisms of transmission remains underdeveloped. This study examined the intergenerational effects of mothers’ adverse childhood experiences on their offspring’s social-emotional development and whether the association was mediated by mothers’ mental health, adult adversity, and perceptions of paternal involvement. The study sample included 831 mothers (19–49 years old, 47.5% White) with children aged 12–48 months who participated in a longitudinal investigation of low-income families in Wisconsin. ACEs were assessed by home visitors, and two waves of survey data were collected by researchers to assess demographics, mediators, and social-emotional outcomes. A path analysis showed that the association between maternal ACEs and children’s social-emotional problems was fully mediated, with postpartum mental health acting as a primary mechanism. Implications for intervention and future research directions are discussed.

Background: Food insecurity is a serious public health problem and is linked to the mental health of children and adolescents; however, its relationship with mental health service use is unknown. We sought to estimate the association between household food insecurity and contact with health services for mental or substance use disorders among children and adolescents in Ontario, Canada. Methods: We used health administrative data, linked to 5 waves of the Canadian Community Health Survey, to identify children and adolescents (aged 1–17 yr) who had a household response to the Household Food Security Survey Module. We identified contacts with outpatient and acute care services for mental or substance use disorders in the year before survey completion using administrative data. We estimated prevalence ratios for the association between household food insecurity and use of mental health services, adjusting for several confounding factors. Results: The sample included 32 321 children and adolescents, of whom 5216 (16.1%) were living in food-insecure households. Of the total sample, 9.0% had an outpatient contact and 0.6% had an acute care contact for a mental or substance use disorder. Children and adolescents in food-insecure households had a 55% higher prevalence of outpatient contacts (95% confidence interval [CI] 41%–70%), and a 74% higher prevalence of acute care contacts (95% CI 24%–145%) for a mental or substance use disorder, although contacts for substance use disorders were uncommon. Interpretation: Children and adolescents living in a food-insecure household have greater use of health services for mental or substance use disorders than those living in households without food insecurity. Focused efforts to support food-insecure families could improve child and adolescent mental health and reduce strain on the mental health system.

A growing body of research reveals a connection between maternal incarceration and various child development outcomes. Even so, little is known about how the timing of maternal incarceration may shape the social-emotional development of young children and the role of maternal mental health in mediating this association. Using a sample of 1097 mothers (18-52 years old, 47.6% white) and children (aged 12-48 months) receiving home visiting services in Wisconsin, this study examined the intergenerational effect of incarceration before a child's birth on child social-emotional development, and whether this association was mediated by maternal mental health. While incarceration prior to a child's birth was not directly associated with child social-emotional outcomes, path analysis revealed an indirect association between mother's incarceration prior to a child's birth and child social-emotional problems through maternal mental health problems. Findings suggest that formerly incarcerated mothers may experience long-lasting mental health concerns that can undermine child social-emotional development. To optimize outcomes, practitioners may consider services that address the mental health, social support, and instrumental needs of mothers and children who have been impacted by mass incarceration.
